4 Claims.

This invention relates to metallic barrels, and essentially to means adapted to be applied to one end of a barrel to clamp and lock an end closure thereon.

An object of the invention resides in the provision of a flexibly resilient split locking ring, and means connected with the ends thereof for expanding, or contracting and locking the split ring in position on one end of a barrel to lock an end closure against displacement thereon.

A further object of the invention resides in the, provision of means in the nature of a lever, provided with a cam portion, adapted to be wedged between the pivot point of the lever and the wall of a flanged barrel closure when swinging the lever to closed position, thereby'pulling the free ends of the split locking ring into tight contact with the closure flange, as well as securely locking the split ring against circumferential displacement upon the removable closure end of the barrel.

. A further object of the invention is the provision of means for locking the split ring expanding and contracting means to, function as a unit, so that said latter means can be swung from closed to open position, without expanding the split ring unless first removing the first means.

The invention possesses advantages in points of simplicity and eDiciency and, is comparatively inexpensive in cost of manufacture. With the above and other objects in view, the invention consists in the novel features of construction, arrangement and combination of parts hereinafter more fully described and finally pointed out in the claims hereto appended.

Referring to the accompanying drawings form-' ing a part of this specification, wherein like characters of reference denote similar parts throughout the several views:

Fig. 1 is a top plan view of a metallic barrel having a removable top closure clamped and locked in position by means embodying the features of my invention.

Fig. 2 is a side elevation of a metallic barrel showing my closure clamping and locking device applied thereto.

- Fig. 3 is a fragmentary view of the flange and wall portion of the top closure, showing a packing ring in position.

Fig. 4 is an enlarged sectional view taken on line 4 4 of Fig. '7.

Fig. 5 is an enlarged sectional view taken on line 55 of Fig. 7.

Fig. 6 is a top plan view of the barrel, similar" to Fig. 1, but showing the closure clamping and locking device in open position and expanding the split locking ring for easy removal from the flange of the barrel head.

Fig. 7 is an enlarged fragmentary view of the barrel closure clamping and locking device in 5 closed position.

Fig. 8 is an enlarged fragmentary view of the barrel closure clamping and locking device in open position.

Fig. 9 is a plan view of a modified split ring 10 expanding, contracting and locking means applied to the removable head end of a barrel, the

means being shown in closed and locked position. Fig. 10 is a view similar to Fig. 9, showing the split ring expanding, contracting and locking l5 means'in open position for expanding the split ring for removal from the barrel head.

In carrying the invention into effect, I employ a suitable, preferably cylindrical metallic barrel body I having an end closure or head 2, which is suitably fixed to the lower edge of the barrel body I, and an end closure or head 3 removably secured to the top end of the barrel body I.

The top edge of the barrel body I is curled or rolled outwardly and downwardly to provide a rolled upper edge 4 therefor.

V The top end closure or head 3 is formed of'sheet metal, and is so shaped, or depressed as to provide a suitable marginal wall 5, which terminates at its upper end in a suitably curved flange 6, as clearly shown in Fig. 3, and, there is adapted to be a suitable flexibly resilient packing ring 1 carried within the inverted annular curved channel formed by curving the closure flange 6.

The top end closure, or head 3 is in the nature of a so-called friction type cover, although the wall 5 of the top closure does not have a friction fit with the wall of the barrel body. The closure 3 is merely mounted within the open end of the barrel with the packing resting and held on the curved flange of the closure resting upon the rolled upper edge 4 of the barrel body I.

The means for clamping and locking the top end closure or head on the end of the, barrel will now be described.

The above means comprises a split ring like member 8 approximately semi-circular in crosssection, so as to be concaved-convexed in form.

The split ring 8 is of sheet metal and when formed is flexibly resilient. A suitable arm member 9 is suitably secured to one end of the split ring such, for instance, as by welding. The outer end of the arm 9 is shaped to conform tothe outer shape of the split ring 8 and it projects 55 towards the center of the split ring 8 a short distance, is then bent downwardly a predetermined distance, as at I8, and it is then bent into horizontal position to provide an ear II which is sition, to provide an ear I4, which is wider than the arm I 2. In other words, the inner end portions of the ears project a suitable distance beyond the opposed .edges of their respective arms 8 and I2, as clearly apparent in Figs. 5 and 8.

A pair of suitable levers designated, generally, as A and B, are pivotally connected together, as at IS, in one embodiment of the invention, to provide relatively short jaw portions I8 and II, respectively, and relatively long, suitably curved, handle portions I 8 and I9, respectively.

The jaw portion Hi of lever A, which is the top lever, is offset, as at 20, and it is pivotally connected, as at 2|, to the ear ll of arm 9, approximately in alignment with the inner edge of arm 9.

The jaw portion ll of lever B, which is the lower lever, is pivotally connected, as at 22, to the under face of the ear l4 of arm l2 approximately in alignment with the inner edge of the arm I2. The free end of jaw portion I! of lever B is wider than the jaw portion iii of lever A, and the outer corner portion thereof is rounded off, or curved as at 23, to provide a cam portion 24 adapted for frictional engagement with the inner face of the wall 5 of the top closure or head 3, as will be apparentfrom Figs. 4 and '7, of the drawings, by wedging itself between the pivot 22 and the wall 5 of the closure head 3.

The levers A and B, when in their open positions, illustrated in one of such positions in Figs. 6 and 8, are spread apart and serve to expand the split ring 8 by spreading the ends thereof apart. The levers are in open positions when the ring is applied to enclose or surround the flange 8 of the top closure 3 and rolled upper edge 4 of the barrel body I after the top closure 3 has been mounted on the open end of the barrel.

After the split ring 8 has been thus applied to the removable closure end of the barrel, the operator grips the handle portions l8 and I! of the levers A and B, and by moving them towards each other, the jaw portions l8 and II of the levers are moved toward each other, thereby moving ears II and I4 to positions so that the ear ll of arm 8 will overly ear l4 of arm l2, thus contracting the split ring 8 by moving the ends thereof toward each other. When the levers A and B have been moved to positions, one above the other, the operator swings both levers, as a unit, from such position to the closed position shown in Fig. '7, which serves to wedge the cam portion 24 of the jaw l4 of lever B into operative position, as shown in Fig. 7, to cause the cam face 23 of the cam 24 to frictionally engage the inner face of the wall 5 of the top closure or head 3 to hold the levers A and B in their closed position and prevent accidental opening displacement of the levers.

After the levers have been moved into their closed positions, which contracts the split ring for clamping the top closure or head 3 to the top of the barrel, the two levers are locked or sealed together to prevent swinging movement of levers r lative to each other, yet permitting opening winging movement of both levers, as a unit, without efiecting expansion of split ring 8 or permitting circumferential displacement of the split ring upon the barrel.

The seal, as shown, includes a wire or like element 25 which is passed through the registered openings 28 and 21 in the handle portions of the levers A and B, respectively, and the ends thereof locked together by means of a suitable seal member 28, which seal must be broken before the handles of the levers can be moved relative to each other for spreading the jaws l6 and IT to expand the split ring by moving the ends thereof away from each other for removal of the split ring 8 from clamping contact with the flange 8 of the top closure and the exposed portion of the rolled edge 4 of the container body I.

When the split ring 8 is clamped into closed position, by contracting the same by means of the levers A and B, the packing ring I between the top closure flange 6' and the rolled edge 4 of the barrel body, is compressed due to the pressure applied thereto by contracting the split ring 8 by means of the levers A and B.

From the foregoing description, it is apparent that when the levers A and B are in their closed or overlying positions, the pivots 2i and 22 are in vertical axial alignment, permitting both levers A and B to be swung upon their respective pivots, as a unit, to positions whereby the cam portion 24 of the jaw ll of the lower lever B is out of wedged contact with the wall 5 of the top closure 3, and thereafter, if the seal is broken, the handles of the levers can be swung upon the pivot ii for moving the jaw portions of the levers apart to effect expansion of the split ring 8, as apparent from Fig. 8.

It will be apparent from Fig. 7, of the drawings, that the relative positions of the pivot points 2| and 22 are such that when the levers are in closed positions, as shown, that accidental swinging movement of the levers to open positions is impossible due to the pivot l5 being closer to the split ring 8 than the pivots 2| and 22, which causes a locking effect, which is assisted by the wedging effect of the cam portion 24 of the lever B.

The split ring expanding, contracting and locking means shown in the modification shown in Figs. 9 and 10, embodies all the features shown in the preceding figures of the drawings, with the exception that I eliminate lever handle I8, and employ a connecting link as a substitute for the jaw portion l6 thereof.

In the modification, the lever B is pivoted a at 22' to the ear l4 midway the side edges of arm l2 instead of in approximate alignment with one of the side edges thereof, as shown in Fig. 8.

The link designated l8, which is employed in lieu of the lever jaw 48 shown in Figs. 1 to 8, is pivotally connected, as at 2|, to the lower face of the ear ll midway the side edges of the arm 9 instead of in approximate alignment with one of the side edges thereof, as shown in Fig. 8, thus the pivots 2| and 22' do not move into axial alignment when the lever B is moved into closed position, as do the pivots 2| and 22 shown in Figs. '7 and 8.

The connecting link l8' is connected to the lowerface of the lever B by means of the pivot designated I8. Where in Figs. 7 and 8, the lever jaw I8 is connected to the upper faces of the lever B and ear II, in the modification the link
